IMPROVEMENT IN CANS FOR HOLDING PAINT, &c.

Specification formingpart of Letters Patent No. 142,612, dated September9, 1873; application led July 21,1873.

To all whom it may concern:

Be it known that I, GEORGE H. GHiNNocK,

of Brooklyn, in the county of Kings and State of New York, have inventedcertain Improve; ments in Cans for Holding Paint, Ste., of which thefollowing is a specification:

This invention is designed for holdingpaints and other thick or viscousliquids 5 audit consists in a novell combination of parts whereby thecontents of the can may be readily ejected therefrom in any desired ordefinite quantity by force applied to a movable head provided to thesaid can and operated without injurious strain upon or liability ofbreakage of the parts. The invention also comprises certain novel meanswhereby the attachment of the screw at the lower part of the can isprovided for without liability of forcing inward the true bottom by theworking of the movable head aforesaid, and whereby the part to whichsuch attachment of the screw is made is firmly held in position againstthe strain exerted by the screw during the movement of the head to ejectthe contents of the can.

Thedrawing represents a central vertical section of a can constructedaccording to my invention.

A is the body of the can, cylindrical in form, and made preferably ofsheet metal. Near its lower end is provided an internal circumferentialrib, a., below which is placed the false bottom B, comprising av disk ofwood, or other suitable material, of any desired or appropriatethickness. This false bottom B is brought snugly against the rib a, soas to be supported thereby against upward or inward strain, and is heldagainst pressure in the opposite or Y downward direction either byhavingthe met-al of the body compressed upon it, or by nails driven throughthe latter radially Vinto the said false bottom. In the center of thislast is a circular hole, through which is passed the cylindrical neck cof an upright screw, C, this neck being of diminished diameter ascompared with the threaded or main portion of the'screw, and therebyaffording a shoulder, a', bearing upon a washer, b', placed upon thefalse bottom to protect the wood from the severe abra-sion of the metalshoulder. A similar washer, c', is placed on the under side of the falsebottom, and has riveted over or upset upon it the lower extremity of theneck c, as shown at a. By lthe means described the screw has a fixedattachment, as concerns vertical or longitudinal movement, to the falsebottom B, and at the same timeis free to turn upon or around its axis.The true bottom, made of sheet metal, of the can is shown at D, and issoldered fast to the body A in the usual manner, as indicated at b. ,Itserves to securely close the lower end of the can, and also to protectthe false bottom `from external injury. At the lower part of the can,just above the false bottom, is an outlet-orifice or spout, d, over orupon which, when desired,

, may be placed the cap c. E is the head or top ot' the can7 madepreferably of wood, or like material, and furnished at its peripherywith a leather or other suitable packing, f, bearing snugly upon theinner surface of the body A. Fixed, by bolts or otherwise, in the centerof the head E is a metallic socket, g, threaded internally to fit thescrew O, which passes through the same, and is squared at g, its upperextremity, to receive the wrench F, whereby it may be turned. The upperend of the screw is diminished in diameter, as shown at i, to provide aneck above the threaded portion of sufficient length to permit the screwto be turned, when desired, until the socket is brought entirely clearof the thread of the screw, to permit, after the detachment of the Whenit is desired to withdraw the whole or.

any part of the contents,the cap eis removed from the outlet d, and thescrew is turned to force downward or inward the hea-d E, which isthereby caused to force the contents out through and from the outlet d,the quantity thus forced out being, of course, in direct ratio to theextent to which the head is depressed, as just set forth.

It will be especially borne in mind that by the attachment of the screwat the bottom of the can, as described, and the arrangement of the headE at the opposite part of the screw, the strain or draft exerted by thelatter upon both the point of attachment and the head is in directionstoward each other, so that there is no tendency to dislocation ordisarrangement of the parts, as would be the case if the head wereforced inward by the thrust of a screw having its bearing on the outerinstead of the inner side of the said head. Furthermore, the rib a.,affording a continuous ledge in contact with the upper edge of the falsebottom, efectually sustains the same in position against the inwarddraft exerted by the screw when operating the head in an inwarddirection. The false bottom, moreover, by enabling the neck cof thescrew to pass through the said false bottom, affords a more effectualhold for the screw, and relieves the true bottom from the strain whichwould be incurred thereby if the screw were attached thereto,-

When desired, the body of the can may be furnished with lugs n, for theattachment of a bail, by which the can may be conveniently carried.

I disclaim the construction and operation of a can for packing andtransporting paints, Snc., as set forth in the patent No. 134,947granted to Hiram Tucker, January 14, 1873; but

Vhat I claim as my invention is l. The can constructed with the outletd, the sliding head E, and the screw C, the latter having its point ofattachment at the lower part of the can, and the whole arrangedsubstantially as herein set forth, whereby, during the expulsion of thecontents of the can from the outlet d, the strain upon the head andbottom portion of the can is in an inward direction, substantially asand for the purpose speci ed.

2. The false bottom B, provided within the can, covered by the truebottom D, and arranged to provide the means of attachment for the lowerend of the screw G, substantially as herein set forth, for the purposespecified.

3. The internal circumferential rib a, formed in the can and arranged tosupport the false bottom B against the inward strain exerted by thescrew during the downward movement of the head, substantially as hereinset forth.
